We should disable NMIs when accessing CMOS ports during state restore,
like it's done during state backup in call32_prep().

Hi all,
We've had reports of users hitting KVM emulation failures in certain workloads
and were able to track down a missing NMI_DISABLE_BIT in call32_post() when
accessing CMOS ports. This patch disables NMIs on state restore, following other
accesses to CMOS_PORT_INDEX throughout the seabios
BUILD_MIN_BIOSTABLE reserves space in the f-segment. Some data
structures -- for example disk drives known to seabios -- must be
stored there, so the space available here limits the number of
devices seabios is able to manage.
This patch adds an config option for BUILD_MIN_BIOSTABLE so the size
